SERVICE RELEASE N43

NATURE OF RELEASE: Change of spark plug grade MODELS AFFECTED: Commando- all models and gears DISTRIBUTION: Worldwide- general distribution EXPLANATION: A new grade of spark plug has been tested extensively (by this company) and found even more suitable than the present recommendation. The new grade - Champion N7Y replaces Champion N6Y and will in future be used as original equipment on all Commando models,   ACTION: It is not necessary to change the grade of plug on any machines. However, as the N6Y plugs reach the end of their useful life, they can be replaced to advantage with the N7Y grade. June 1971 Norton Villiers Canada Limited
